CLOMIPHENE CITRATE IN THE MANAGEMENT OF ANOVULATORY UTERINE BLEEDING

Estriol in the management of the menopause

Tzingounis VA et al., 1978 · JAMA

Estriol was administered for a six-month period as estrogen replacement therapy to 52 symptomatic postmenopausal women. Assays of serum follicle-stimulating hormone (FSH), luteinizing hormone (LH), estrone, and estradiol were performed before and during therapy. During this period of administration, vaginal cytology, cervical mucus, and endometrial studies were performed. Clinical effectiveness was directly related to dosage (2 to 8 mg/day). Estriol (8 mg/day) failed to induce endometrial proliferation and proved a poor suppressor of FSH and LH. This agent's capacity to relieve vasomotor instability and improve vaginal maturation without notable side effects is sufficient reason to include this drug in the management of the postmenopausal syndrome.

Update on the safety and efficacy of clomiphene citrate as a therapeutic agent

Asch RH et al., 1976 · J Reprod Med

Fifteen years have passed since our group first proposed the use of clomiphene citrate as an ovulation-inducing agent. Our 15-year experience with over 2,000 patients has not dampened our enthusiasm for this drug. The benefits have far outweighted the minor side effects or the possibility of multiple births. Serious birth defects were minimal and have been no greater than what one may expect in the general population. Clomiphene citrate has been a boon to womankind and deserves the confidence of both patient and physician: it is a drug with a record of utility and with but minor risks.

CLOMIPHENE CITRATE: FURTHER OBSERVATIONS ON ITS USE IN INDUCTION OF OVULATION IN THE HUMAN AND ON ITS MODE OF ACTION

Roy S et al., 1963 · Fertil Steril

Induction of ovulation in the human has been of considerable research interest for several decades. Various hormonal regimens and other procedures have been tried in the past.1 • 2 In spite of all these trials, the problem of ovulatory failure remains a frustrating dilemma for the physician. Recently, the induction of ovulation with clomiphene citrate in about 70% of anovulatory women was reported by our group.3- 6 It was felt that an important breakthrough in this difficult field of endeavor was at hand. 7- 9 Our observations have been confirmed by other groups of investigators.10- 12 The present report embodies a detailed analysis of the results of administration of this agent to 200 women, of whom 179 were anovulatory. The results of our studies on the probable mode of action of this drug are also discussed.

Induction of ovulation

Experience with induction of ovulation

MacLeod SC et al., 1970 · Am J Obstet Gynecol

One hundred and thirty-five patients diagnosed as ovulatory failure have been treated in our clinic since 1966. One hundred and eighteen of these have been treated with clomiphene citrate, or more recently, its cisisomer, and 17 patients with long-standing secondary amenorrhea or primary amenorrhea have been treated with human menopausal gonadotropins, in combination with human chorionic gonadotropins. Of the latter group, 14 of the 17 were shown to be capable of response to exogenous gonadotropins and 12 of these ovulated and 7 (50 per cent) became pregnant. The over-all ovulatory rate with clomiphene citrate or its cisisomer was 78 per cent, with a pregnancy rate of 31 per cent. The results of our present investigation with clomiphene citrate in 10 and 20 mg. dosage are presented in detail, and compared with our previous experience with clomiphene. It appears that cisclomiphene 20 mg. is as effective as clomiphene citrate 100 mg., but has the decided advantage of fewer side effects associated with its use. With the human menopausal gonadotrophins, no major complications, such as ovarian overstimulation or multiple pregnancies, were encountered, and we feel this is attributed to careful selection of patients and daily tracking of total urinary estrogens.

Evaluation of a new ovulatory stimulating agent: clomiphene citrate (clomid)

No Authors Listed, 1968 · JAMA

Clomiphene citrate, in selected patients, is an effective agent for the treatment of infertility due to anovulation. An adequate laboratory and physical evaluation of each individual patient is essential for proper use of the drug. The major adverse reactions encountered are ovarian enlargements and cysts; in most patients, these conditions regress spontaneously after withdrawal of the drug.

A prospective randomized trial comparing clomiphene citrate with tamoxifen citrate for ovulation induction

Boostanfar R et al., 2001 · Fertil Steril

To compare the rates of ovulation and pregnancy after tamoxifen citrate (TMX) or clomiphene citrate (CC) among anovulatory women with infertility. Prospective randomized trial. Infertility clinic in a university teaching hospital. PATIENT(S): Eighty-six anovulatory women under 40 years of age undergoing ovulation induction. INTERVENTION(S): The women were assigned randomly to receive either TMX or CC on cycle days 5-9. MAIN OUTCOME MEASURE(S): Rates of ovulation and pregnancy for the two treatment modalities. RESULTS(S): The overall rate of ovulation in the TMX group was 50 of 113 (44.2%) and in the CC group, 41 of 91 (45.1%). There were 10 pregnancies in the TMX group and 6 pregnancies in the CC group. The cycle fecundity per ovulatory cycle was 20.0% in the TMX group and 14.6% in the CC group. CONCLUSION(S): The overall rate of ovulation and pregnancy were similar with TMX and CC. TMX is a suitable alternative agent to CC in the management of anovulatory infertility.
